Insights
The single nucleotide polymorphism miR-146a rs2910164 G allele is linked to a reduced risk of coronary heart disease (CHD). This meta-analysis confirms its association with lower CHD susceptibility, particularly in the Chinese population.
Area of Science:
- Cardiovascular Genetics
- Molecular Epidemiology
- Atherosclerosis Research
Background:
- Coronary heart disease (CHD) is a major manifestation of atherosclerosis with high morbidity.
- MicroRNA (miRNA)-146a rs2910164 polymorphism has been implicated in CHD risk, but findings are inconsistent.
- This meta-analysis aimed to clarify the association between rs2910164 and CHD susceptibility.
Approach:
- A comprehensive literature search was conducted across major databases until April 2022.
- Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the correlation.
- Bonferroni correction and trial sequential analysis were employed to ensure result reliability.
Key Points:
- The meta-analysis included 18 studies with 6859 cases and 8469 controls.
- The G allele at rs2910164 was significantly associated with decreased CHD risk across multiple models.
- Subgroup analysis indicated a lower CHD risk in the Chinese population with the G allele or GG genotype.
Conclusions:
- MicroRNA (miRNA)-146a rs2910164 polymorphism is potentially associated with reduced coronary heart disease susceptibility.
- The G allele appears protective against CHD, especially in specific populations and genetic models.
Background:
Coronary heart disease (CHD) is one of the manifestations of atherosclerosis with a high morbidity rate. MicroRNA (miRNA)-146a rs2910164, a single nucleotide polymorphism, is associated with the progression of CHD risk. However, the results are controversial and uncertain. Therefore, an updated meta-analysis was conducted to evaluate the association between rs2910164 and CHD susceptibility.
Methods:
PubMed, Cochrane Library, EMBASE, Web of Science, China's National Knowledge Infrastructure, VIP, and Wan fang were searched for the eligible articles until April 30, 2022. The odds ratios (ORs) with 95% confidence interval (CIs) were calculated to assess the correlation. Bonferroni correction was utilized between multiple comparisons. Trial sequential analysis was performed to measure the required information size and assess the reliability of the meta-analysis results.
Results:
A total of 18 eligible studies, including 6859 cases and 8469 controls, were analyzed in our meta-analysis. After Bonferroni correction, we found that the G allele at rs2910164 was associated with significantly decreased CHD risk in the allelic model (OR = 0.86), homozygous model (OR = 0.79), and heterozygous model (OR = 0.89) in total population. In the subgroup analysis, the subjects containing the G allele and GG genotype were associated with a lower risk of CHD in the Chinese population, not the GG + CG and CG genotype. In addition, under the allelic, homozygous, heterozygous, and dominant models, miR-146a rs2910164 was at lower CHD risk in the large size population except in the recessive model.
Conclusion:
These results show that miR-146a rs2910164 might be associated with lower CHD susceptibility.
